    • An optical coherence tomography apparatus includes a light source, a light coupling module, and an optical path difference generating module. The light source emits a coherent light. The light coupling module divides the coherent light into a first incident light and a second incident light. The first incident light is emitted to an item to be inspected and a first reflected light is generated. The second incident light is emitted to the optical path difference generating module, a second reflected light is generated according to the second incident light by the optical path difference generating module through changing the transparent/reflection properties of at least one optical devices of the optical path difference generating module, so that there is a optical path difference between the first reflected light and the second reflected light.
    • 光学相干断层摄影装置包括光源,光耦合模块和光路差产生模块。 光源发出相干光。 光耦合模块将相干光分成第一入射光和第二入射光。 第一个入射光被发射到要检查的物体,并且产生第一反射光。 第二入射光被发射到光程差产生模块,通过光路差产生模块根据第二入射光产生第二反射光,通过改变光路的至少一个光学器件的透明/反射特性 差分发生模块,使得在第一反射光和第二反射光之间存在光程差。
